Sprint Qualifying will make it's F1 debut next weekend at the British Grand Prix and Helmut Marko believes that one false step on Friday could ruin the entire three days for a team and driver.
The format will see one practice session on Friday before a traditional qualifying format later that day to determine the Sprint Qualifying on Saturday. The 100km even will have no pit-stops and the result will be used for Sunday's grid, however Marko is wary of what might happen if things go wrong on Friday.
"If something goes wrong on Friday, it can ruin the whole weekend," Marko told Speedweek. "The first practice session is the only chance to check your form, after that the parc ferme regulation comes into force.
"That means you can only correct something on Saturday in the second practice session."
Red Bull head to Silverstone with a 44 point lead over Mercedes in the Constructors' Championship, while Verstappen has a 32 point advantage over Lewis Hamilton. Although things are trending in the right direction for the Milton Keynes outfit following five wins in a row, Marko thinks Mercedes won't give up easily.
"Mercedes only gives up then there is no mathematical chance," Marko added.
